Put out the fire with explosive

[Chitose]

Hello, Chitose wonder chick again.

First, This is NOT my homework.
...........
I herd theory that we can quickly put out the fire by setting explosive right next to it. Suck away oxygen or something I'm not sure

I wonder is this theory is true?

If it's true how come?

Is explosion burn out oxygen in the instant? or blast power push oyxgen around it away and create instant vacuum area?

and... is this physic?

...........
PS. English is not my native languge, forgive me if I'm wrong in gramma or spelling.

Yes a fire can be put out this way. It is often used to put out http://en.wikipedia.org/wiki/Oil_well_fire" . It works by consuming all of the locally available oxygen.

It doesn't work like that.

An oil fire is a cloud of oil-vapour that's burning above a liquid oil. The heat from the vapour evaporates more oil. If you put an explosive next to it you blow the vapour and its heat away from the liquid oil. This will separate the fuel from the heat. It's really the same as blowing out a candle.

I was quoting what was in the article:

Oil well fires are more difficult to extinguish than regular fires due to the enormous fuel supply for the fire. In fighting a fire at a wellhead, typically high explosives, such as dynamite, are used to consume all the local atmospheric oxygen and snuff the flame out. Doing so removes the oxygen necessary for the fire to burn, but the fire's fuel, whether it be natural gas or oil, is still present which can shower down upon the working crew.
